intense,

Application filed January 4, 1913.

To all whom it may concern Be it known that I, ALFRED HAoKn'rr, of the city of Toronto, county of York, Province of Ontario, Canada, machinist, have invented certain new and useful Improvements in Steam-Generators, of which the following is a specification.

My invention relates to improvements in steam generators, and the principal object of my invention is to design a steam generator to be used in connection with hydrocarbon gas producers, and more particularly with the type of hydrocarbon gas producer disclosed in my pending application No. 723072, filed September 30th, 1912.

Another object of my invention is to design a steam generator so that the surplus heat from the means for generating the steam shall be used to superheat the steam, and my steam generator comprises a reservoir for storing the steam and in which the same expands; one or more vaporizing pans constantly in communication with said reservoir; a conduit mounted in the upper portion of said reservoir and opening through the head and back sheets thereof, and a suitable casing housing said vaporizing pan and the means for generating steam therein, the said conduit having communication with the interior of said casing, as hereinafter more particularly set forth.

Figure 1 is a vertical longitudinal section on the line 3-3, Fig. 2, the burners; distributing tubes; generator tubes; in the hydrocarbon gas producer illustrated, together with their reservoir or tank or drum and most of the piping, being shown in side elevation. Fig. 2 is a vertical cross section on the line 2-2, Fig. 1. Fig. 3 is a central longitudinal section through the outer end of a suitable gas generator forming part of the hydrocarbon gas producer illustrated for generating steam, showing means where by the controlled oil and steam are fed thereinto. Fig. 4- is, in part, a vertical longitudinal section through a suitable type of burner to be used on the hydrocarbon gas producer I prefer to use with my steam generator, and Fig. 5 is a side elevation, with the lower end shown in section, of one of the water pipes mounted in the vaporizing pans of my generator.

Specification of Letters Patent.

Serial No. 740,173.

In the drawings, like characters of reference indicate corresponding parts in each figure.

A is the reservoir. Opening through the head and back sheets B and C respectively, and held therein, is a conduit 1). The vaporizing pans E are preferably provided with flanges F so that these flanges may be secured to the head sheet B by any suitable means such as rivets G. Each vaporizing pan communicates with the reservoir A by means of an opening H, formed in the head sheet 13. It will be noticed that I illustrate two vaporizing pans E, although one only may be used if desired. These vaporizing pans, together with the means for generating steam in my generator, are housed within a casing I so that the surplus heat arising from the means used to generate steam shall not be wasted, but be utilized as hereinafter particularly set forth.

I shall describe my preferred means for generating steam in my steam generator, which is a suitable form of hydrocarbon gas producer. Each unit of the lower hydrocarbon gas producer illustrated comprises a generator tube 2, the outer end of which is threaded and screws into the internally threaded end 3 of a head-member C. This head-member is preferably provided with a flange 5 through which rivets 6 pass so as to secure the same to the front wall 7 of the casing I.

8 is a suitable tank or drum mounted within the casing I, and to one end of this drum is connected the manifold 9 by means of the couplings 10.

Each of the generator tubes 2 screws into the manifold 9 of its unit, and positioned underneath each generator tube is a distributing tube 11 which is connected by the couplings 12 to the tank or drum 8.

Carried by each distributing tube 11 are burners of any suitable construction. I prefer however, to use burners which comprise burner tubes 121 which are supported by the distributing tubes 11. Each burner tube 121 supports a mixing tube 13 suitably coupled thereto, and the bottom of each tube is open, as shown at 1st, and in the bottom portion of each mixing tube is pro vvided a plurality of air holes 15.

Each head member is provided with an oil chamber 16 and a passage-way 17 separated therefrom by a wall 18.

19 is a needle valve which is suitably carried by each head-member 4, and each needle valve operates to control an opening 20 formed in the wall 22 of each head-member 4.

From any suit-able source, steam enters each head member through a pipe 23, and from any suitable source the oil enters each head member through the pipe 2 1. The gas generated within the generating tubes 2 of the lower hydrocarbon gas producer escapes into the tank or drum 8 through the connections already described and in due course it is consumed by the burners mounted on the distributing tubes 11 of this lower hydrocarbon gas producer. The manifold 25 of the upper hydrocarbon gas producer is connected by the couplings 26 to one end of the tank or drum 8. The manifold 25 is also provided with a plurality of generating tubes 27, and coacting with each of these generating tubes is a distributing tube 28, each of which is connected by a coupling 29 to the tank or drum 8. The distributing tubes 28 are of course provided with burners.

Associated with each vaporizing pan E is a water pipe 30 from which open branch pipes 81, which extend into the said vaporizing pans. The lower end 32 of each branch pipe 31 is closed as illustrated in Fig. 5, and in the side of each branch pipe, preferably at an angular position, is formed a hole through which the water escapes into each vaporizing pan. The water within the said vaporizing pans is in due course tu led into steam and passes into the reservoir A whence it is drawn off to point of consu aption by any suitable dome 3 1- carried by the said reservoir.

Upon referring particularly to Figs. 1 and 2 it will be seen that the conduit D is positioned near the top of the reservoir A, and since the said conduit opens into the casing I the surplus heat within said casing must of necessity pass through said conduit and during its passage therethrough the same superheats the steam within the reservoir A.

The reservoir A is of course supported by any suitable means such as blocks a and of course it will be so protected as to prevent the cooling off of the steam therein.

Upon referring to Figs. 1 and 2 of the drawings, it will be observed that the vaporizing pans E are quite shallow, thereby affording a very large heating area on the bottom side of each vaporizing pan so that the comparatively thin layer of water within each vaporizing pan will be readily converted into steam. Fig. 1 particularly discloses the fact that the pipes 31 open into the said vaporizing pans in position well removed from the openings H. This point of construction, together with the construc tion illustrated in the preceding paragraph prevents any possibility of water escaping into the reservoir.

In the type of hydrocarbon gas producer illustrated and described in this specification, I preferably use the tank or drum 8 so that componentparts of the manufacturel gas will be thoroughly mixed before consumption.

Various changes in construction may be made in the generator illustrated in the drawings forming part of this specification without departing from the spirit of this invention.
